Abstract

"DISPOSITIVO TENSIONADOR PARA CORREIAS". O dispositivo tensionador (1) compreende uma placa de suporte (2) anexada a um pivó (3) que define um primeiro eixo (A); um elemento tubular intermediário (15) acomodando dito pivó (3) e sendo capaz de girar em torno de dito primeiro eixo (A); uma polia (4) suportada por dito elemento tubular (15) por meio de um mancal (26), circundando dito pivó (3) e sendo capaz de girar em torno de um segundo eixo (B) que não é coincidente com dito primeiro eixo (A); e um elemento elástico (27) interposto entre dito pivó (3) e dito elemento tubular intermediário (15) de modo a impelir elasticamente dito elemento tubular intermediário (3) contra dita correia (5). Para garantir que a correia (5) seja centrada com respeito à polia (4) e que as cargas aplicadas ao mancal (26) passem precisamente através do centro das esferas (31) do mancal, a polia (4) é de formato convexo."TENSIONING DEVICE FOR BELTS". The tensioning device (1) comprises a support plate (2) attached to a pivot (3) that defines a first axis (A); an intermediate tubular element (15) accommodating said pivot (3) and being able to rotate about said first axis (A); a pulley (4) supported by said tubular element (15) by means of a bearing (26), surrounding said pivot (3) and being able to rotate around a second axis (B) that is not coincident with said first axis (THE); and an elastic element (27) interposed between said pivot (3) and said intermediate tubular element (15) in order to elastically urge said intermediate tubular element (3) against said belt (5). To ensure that the belt (5) is centered with respect to the pulley (4) and that the loads applied to the bearing (26) pass precisely through the center of the balls (31) of the bearing, the pulley (4) is of a convex shape.
